Measuring the Nipple

The caliper used to measure the nipple

This picture is to show how we measure the length of the ferrule

As one rotates the ferrule in the direction of the orange arrow the measurement we get changes.

You try to make the ferrule parallel to the caliper to get an accurate measurement

In addition as you rotate the caliber around the nipple the measurement changes. Note, we just started this yesterday so its possible the polished

part nipple could be contributing to this effect

These 2 effects are why I’m getting a variation in the measurement.

As long as the variation is small compared to the tolerance we are OK
